摘要
We present a class of exact solutions of the generalized nonlinear Schrodinger equation with time- and space-modulated coefficients, which describe the evolution of wavefunction in various types of external potentials including the harmonic and double-well potentials. The results show that there exist a general condition linking these distributed coefficients, under which the exact solutions can be obtained. Moreover, the evolution of such solutions can be effectively controlled by these distributed coefficients. (C) 2011 Elsevier B.V. All rights reserved.
